  • Publication number: 20230022589
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.

  • Publication number: 20220370177
    Abstract: Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.

  • Publication number: 20220313405
    Abstract: Various embodiments for cleaning carious regions of a tooth are disclosed herein. For example, a dental apparatus can include a fluid platform having a chamber sized and shaped to retain fluid. The chamber can be configured to be coupled to the tooth over the carious region. A pressure wave generator having a distal end may be configured to be positioned in the chamber. The pressure wave generator may be configured to generate pressure waves in the retained fluid sufficient to clean the carious region.

  • Publication number: 20220296346
    Abstract: Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

  • Publication number: 20220233291
    Abstract: An apparatus for treating a tooth includes a proximal chamber and a distal chamber disposed distal the proximal chamber and in fluid communication with the proximal chamber by way of a transition opening. The distal chamber includes an access opening disposed apart from and distal to the transition opening, the access opening to provide fluid communication between a treatment region of the tooth and the distal chamber. The apparatus includes a liquid supply port disposed to direct a liquid stream into the proximal chamber and over at least a portion of the transition opening. The apparatus includes an impingement member arranged within a path of the liquid stream, the impingement member having one or more surfaces positioned to redirect at least a portion of the liquid stream across at least a portion of the transition opening.

  • Publication number: 20210106402
    Abstract: An apparatus for treating a tooth can include a fluid platform comprising a wall and a chamber at least partially defined by the wall. The fluid platform can be disposed against a tooth to retain fluid in the chamber and provide fluid communication between a treatment region of the tooth and the chamber by way of an access port. The chamber can have a central axis. A liquid supply port can be disposed to direct a liquid stream across the chamber along a stream axis non-parallel to the central axis. A suction port can be exposed to the chamber. The chamber can have a maximum lateral dimension in a plane extending substantially transverse to the central axis, the plane delimited by the wall along a boundary. A projection of the suction port onto the plane can be closer to the boundary than to the central axis of the chamber.
